When you cut the holes in your ct for the ports, the ct will go out of shape big time. Tack weld the bottom of the ct to a strong plate before you cut the holes and weld the port rings in, then you can remove the plate.<br>

Was<br>
thinking if there were any stress in the shell after the<br>
rolling, it would tend to distort due to weakening after<br>
cutting out the hole.<br>

Hi André<br>
<br>
Not such a issue wit a plasma cutter.<br>
<br>
The full penetration welds will cause<br>
more<br>
distortion.<br>
Temporery reinforfment<br>
okay.<br>

Distortion when cutting in<br>
shell<br>
<br>
<br>
<br>
Hi all,<br>
<br>
<br>
When you cut out the hole for the conningtower, is<br>
distortion of the shell<br>
an issue?<br>
<br>
<br>
My shell is 12mm in thickness. Wondering if I should<br>
place a reinforcement<br>
ring on either side of the hole to be cut -Not welding them<br>
so I can remove them<br>
after I have tacked the tower in place.<br>
<br>
<br>
<br>
<br>
Thanks<br>
André<br>
<br>
